Below specify the operating type of equipment of the present utility model.
At first according to general operating type, the four-way three-way valve (not shown) of being burn-on respectively by the construction upstream end of pipeline and downstream part at conveyance fluid, two casings 40 are connected on the four-way three-way valve by the flange 39 of oneself respectively, and casing 40 is connected with this valve.Couple together with the by-pass hole 33 of pipeline then, be used for,, constitute by the bypass of construction pipeline by the pipeline between two by-pass holes 33 in process to construction in future of pipeline with two casings 40, unaffected to guarantee ducted FLUID TRANSPORTATION.
Because the operation of upstream end and downstream part is carried out simultaneously, and mode is the same, therefore below only with regard to perforate, the shutoff of upstream end with send and block up the cake operation and be described.
First step operation is perforate.
As shown in Figure 1, at first tube cutter 35a and center drill 36a are fixed on the flange 241 of main shaft, then whole work feeder 11 are installed on the support 1.By opening 401 tube cutter 35a and center drill 36a are sent in the casing 40, then with casing 40 sealing, and the support 1 that will have a work feeder 11 is fixed on the casing 40, thereby installs the first time of finishing entire equipment.
Make by operating mechanism 501, make gear 5 and gear 6 engagements.Starting electrical machinery 4, the rotation of motor output shaft by gear 5,6, worm gear- endless screw 27,26, gear 29,28, transmission shaft 9a, gear 23,22, passes to main shaft 24, and main shaft 24 is rotated, thereby drives the rotation of tube cutter 35a and center drill 36a.At this moment operator are at device external rotation crank 301, by worm gear- endless screw 30,31, gear 32,2, transmission shaft 9b and nut 10, realize the axial motion of main shaft when rotating, thereby driving tube cutter and center drill enters in the above-mentioned four-way tridirectional valve through casing 40, to being cut, finish the perforate task by the construction pipeline.
Although do not illustrate, should be appreciated that to be on the tube cutter, should have a lot of holes, be used for guaranteeing the circulation of fluid in the construction pipeline.But also should be provided with the iron filings recover, because these settings are prior art, do not describing here.
After pipeline was blocked, operator controlled rocking handle 301, made the main shaft band tube cutter and center drill and retreated, retreat into the rear portion of valve 38, throttle down 38 then always, because the existence of above-mentioned four-way tridirectional valve, therefore the fluid in the pipeline still can or not leak through four-way tridirectional valve proper flow.Work feeder is pulled down from casing 40 together together with tube cutter and center drill then.Then tube cutter and center drill are pulled down from main shaft.

Stop the motion of main shaft 24 then, pull down second screw rod 16 and flat key 18, and first nut 15 is rotated along pull bar 17, contact with nut 13 until nut 15, because nut 13 and screw rod 14, nut 15 can not produce further axial motion but still the energy axial motion, therefore the further rotation of nut 15, railing 17 is moved downward with main shaft 24 relatively, from the center hole of main shaft 24, stretch out, promotion shutoff axle 36b, it is moved downward, the motion of shutoff axle 36b becomes near 90 degree the angle between itself and the connecting rod 37b, makes connecting rod overhanging, and occluding body is pressed onto on the tube wall for the treatment of shutoff place tightly.In addition because the pressure of pipeline inner fluid, so occluding body tightly shutoff in pipeline.
At this moment, the fluid in pipeline is by the downstream proper flow of upstream, bypass and the pipeline of pipeline.And, do not have fluid to pass through by in the pipe section of shutoff, operations such as therefore can changing, relocate.
After this replacing that need carry out, operation such as relocate are finished, just need open shutoff.At this moment, backward rotation nut 15 makes itself and nut 12 have certain distance, then screw rod 16 is loaded onto, by will drawing on the pull bar 17 screw rod 16 and cooperating of nut 15.Thereby make the initial angle between connecting rod 37 answers and the shutoff axle 36b, refill flat key 18, by the backward rotation of main shaft 24, occluding body is mentioned, then, throttle down 38, and plugging device and work feeder pulled down from casing, and then whole plugging device is pulled down from work feeder.
The 3rd step is for sending stifled cake operation.
As shown in Figure 3, flange 34c is threaded onto the lower end of pull bar 17, again a stifled cake 35c is fixed on the flange 34c, by above-mentioned similar step, to block up cake 35c sends in the casing 40, first, second and third nut 15,13,12 and first and second screw rod 14,16 all are fixed into as shown in Figure 2, to guarantee the co-rotation of main shaft 24 and connecting rod 17.Open valve 38, by operating mechanism gear 6 is cooperated with gear 3 simultaneously, by worm gear- endless screw 30,31, gear 32,2, transmission shaft 9b and nut 10, make the rotation of motor become the rapid axial motion of main shaft 24, stifled cake 35c is delivered in the four-way tridirectional valve of flange 39 front portions.A fixing device (not shown) is used for stifled cake is fixed on this position, and this fixing device is no longer described here owing to be prior art.Unload flat key 18, screw rod 14 then, pull bar 17 is broken away from and the fixedlying connected of main shaft 24, operator utilize a clamping device to clamp the rectangular cross-section portion on pull bar top then, rotating tension bar breaks away from and being threaded of flange 34c pull bar 17, and then pull bar 17 is fixedlyed connected with main shaft, starting electrical machinery, make the main shaft band pull bar and return, pull down from casing 40 with whole work feeder 11 then, throttle down 38 has promptly been finished whole tasks.In addition, also can see an one-way valve that is arranged in stifled cake 35c from Fig. 3, it cooperates with an existing opening device, and when the main shaft band pull bar and retreated, this opening device will make the one-way valve short time open, and guarantees to block up the equal of downforce on the cake.
By above-mentioned, can know that equipment of the present utility model only just can be finished whole perforates, shutoff with one and send the operation of stifled cake, fast convenient, volume is little.And the connection between the equipment self just constitutes bypass, does not need to be provided with extraly bypass again, and in addition, shutoff of the present utility model utilizes the discharge pressure in the pipeline to carry out, and pressure is big more, and effect is good more.
